your favorite Dark Brown shoe style

If you could have just one dark brown pair (in addition to shoes in other colors), which would it be? Is there a quintessential style for dark brown? Do you just have favorite pair? Pics or links appreciated but not necessary. Thanks.

I have not met mine yet, probably will have to go bespoke to get the blackest of brown [or the right patina] possible. One formal and one casual as far as styling, probably. Will remember to post once I have some.

While my favorite are my G&G wholecut chelseas with an antique brown finish, I'm not sure if they are as versatile as my 2-eyelet JM Weston derbies, also in an antique brown. But seeing neither is suitable for the more formal occasions, they are probably, on balance, equally versatile. As far as brown, either or both are what I would want.
